1. An antenna structure comprising a planar radiating and ground plane connected to each other with a shorting conductor but are otherwise air insulated from each other, said radiating element having a slot extending to its edge, said slot dividing the radiating element, viewed from its feed point, into two branches to provide two separate operating frequency bands, said antenna structure further comprising dielectric material located, as viewed from the direction of a normal of the planar radiating element, substantially inside contours of the planar radiating element and covering at least partly the electrically farthest areas of the outer surfaces of said branches as viewed from said feed point, to increase the bandwidth of the antenna structure.
